VDB 141 (Sharpless 2-136): Ghost Nebula

Revision title: Slight histogram adjustment

Van den Bergh 141, a.k.a. Sharpless 2-136, is a reflection nebula of low surface brightness in the constellation Cepheus that has gained a lot of recognition among amateur imagers in recent years. The central bright region is a Bok globule, while the dark cloud at the right is thought to conceal a binary star system in the early stages of formation. [1,2] While this object is often captured in a wider field view, I took the difficult road and imaged it at 1800 mm focal length, as usual. The image is composed of forty-eight 15-minute luminance subs and nine 30-minute RGB subs for 16.5 h integration.

Description: This is a 2021 revision of my best image from 2014. My retired Atik 383L+ camera produced noisy data even from dark skies, because it really needed to be cooled to -30C to perform well. This image was taken in hot Texas weather in the summer, so I had to take 15 minute subs, and lots of them, to get usable LRGB data. Those long subs overexposed the brighter stars badly. Looking back at the raw data makes me very thankful for modern cameras. The revision (done in GIMP) has standard noise reduction blended with Topaz AI Clear to bring the noise levels down.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
